'Declaration Public ReadOnly Property EventManager As UltraExplorerBarEventManager
public UltraExplorerBarEventManager EventManager {get;}
The EventManager provides a high degree of control over how the control invokes event procedures. You can use it to selectively enable and disable event procedures depending on the context of your application. You can also use the event manager to return information about the state of the control's events.
The event manager's methods are used to determine the enabled state of an event (UltraExplorerBarEventManager.IsEnabled), to selectively enable or disable events (UltraExplorerBarEventManager.SetEnabled), and to determine whether an event procedure is currently being processed (UltraExplorerBarEventManager.InProgress).
